| Crossley Motors Ltd. -2- 19.9.38. Our recommendation here is to have no grooves in the big end, but to have two holes in the crank pin equally and oppositely opposed, and in the top half of the big end bearing one hole which in turn will register with the holes in the crank. Yours faithfully, For ROLLS-ROYCE LTD. | ||
